| 摘 要： | 以实际养猪沼液为研究对象,考察分步进水间歇曝气序批式生物反应器(IASBR)在低温条件下的脱氮性能.结果表明:IASBR反应器的硝化性能临界水温为10℃,水温低于10℃时硝化性能急剧下降,水温10℃以上时氨氮去除率达到90%以上,且水温15℃以上氨氮负荷极限可达到0.30 kg·m~(-3)·d~(-1);低碳氮比(COD/TN)1.7±0.3条件下,反硝化性能临界水温为20℃,20℃以上时TN去除率可保持在80%以上,最高达90%,20℃以下时脱氮效率明显降低,出现亚硝态氮积累现象.此外,IASBR反应器脱氮除磷效率高,温度对TOC和TP去除率的影响不敏感.不排泥条件下,进水COD/TN为3.1±0.4时,TN去除率高达90%以上,TOC和TP去除率分别高达83.6%±3.9%和58.5%±17.8%;随后COD/TN降低至1.7±0.3后,TN去除率仍高达80%以上,TOC和TP去除率仅略有降低分别为77.3%±4.6%、53.1%±10.1%.
